Fedora + Phosh for PinePhone

[ppuser1998]

So, I'm attempting to use the Fedora "minimal" images from ftp://pine.warpspeed.dk/nightly/pinephone/ .
The F34 images seem to boot and work perfectly on my pinephone.
The F35 images don't boot at all. It seems like the boot partition is different between the two:

F35 (note EFI):
Device Boot Start End Sectors Size Id Type
/dev/sdb1 * 2048 1230847 1228800 600M ef EFI (FAT-12/16/32)
/dev/sdb2 1230848 3327999 2097152 1G 83 Linux
/dev/sdb3 3328000 12582911 9254912 4.4G 83 Linux

F34:
Device Boot Start End Sectors Size Id Type
/dev/sdb1 * 2048 1230847 1228800 600M 83 Linux
/dev/sdb2 1230848 3327999 2097152 1G 83 Linux
/dev/sdb3 3328000 12582911 9254912 4.4G 83 Linux

Any advice? Thanks!
